Analysis of off-farm work decisions among smallholder farm households in Burkina Faso

This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity.     

Reproductive health services: “Business-in-a-Box” as a model social innovation

Access to reproductive health services and products in remote and rural communities is a critical area of concern for developing countries. This article considers a pilot intervention in three districts of Pakistan where “Business-in-a-Box” as a model of place-based social innovation is used to improve the socio-economic conditions of women in remote rural settings through socially responsible micro-franchising. It finds that such programmes help build a sense of community, ownership and grassroots capabilities and skills. The article also discusses the impacts of such actions on the individual and community life, and the need to upscale and sustain these initiatives.     

从文本注释到文化传播——由莫言短篇小说的日译本谈起

藤井省三和吉田富夫为莫言作品的日本译介做出了巨大贡献，但二者的译本在翻译策略、语言风格、以及细节构成上存在着诸多差异。单就“注释”而论，藤井省三较多关注对中国历史文化现象的解释，吉田富夫则把重心放在了词汇本身，这种注释策略的差异也在日本读者中间产生了不同的反应，影响了各自译本的传播和接受。由此，从传播学的角度来看，中国作品外译应该遵循“读者优先”原则，在挑选适当原本的基础上，平衡“异化”和“归化”的比例，加强中外译者的交流合作，采用贴近对象国读者的表述，以便更好地推进中国文化“走出去”战略。     

制度差异与制度创新:多元制度互动下的大湾区改革

在一国两制的背景下,香港、澳门与内地之间的制度差异如何影响粤港澳大湾区的发展?学界对此仍关注不足。论文基于制度主义理论,构建了"制度差异-张力-制度创新"的理论框架,以深圳前海自贸区的工程建设管理制度改革为案例,分析了制度差异推动改革创新的机制。研究发现,不同的制度逻辑形塑行动主体的认知与行为,因此多元制度在互动中能够产生张力,进而激发行为主体的能动性,促使其反思、设计新的制度、采取改革行动,最终促成制度创新。中国内地与港澳的制度在"一国两制"方针下得以多元共存,制度差异在粤港澳密切互动中产生的张力是大湾区改革的创新源泉,使大湾区在国家改革与发展大局中发挥重要作用。     

What do forensic analysts consider relevant to their decision making?

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making.     

Managing commercial risks in open source software licensing

Legal context: The article reviews the commercial risk allocation clauses intypical open source licence terms and discusses their enforceabilityand implications. Key points: The enforceability of warranty disclaimers and limitation ofliability clauses in common open source licence terms is questionable,particularly in a cross-border context, and commercial licensorsshould take additional steps to protect themselves from down-streamrisks. Practical significance: Open source software presents a number of unusual commercialissues, because it is available free of charge and the providerstry to disclaim warranties and liabilities. End users and resellershave to adjust their own in- and out-licensing models to accommodatethis situation.     

鸡IFN-γ重组鸡痘病毒对鸡传染性腔上囊炎MB43弱毒疫苗免疫鸡免疫应答的影响

将重组鸡痘病毒(rFPV-IFN-γ)与IBD MB43弱毒疫苗联合接种SPF鸡,研究重组鸡IFN-γ对IBD疫苗免疫效果的影响.结果显示,rFPV-IFN-γ和MB43弱毒疫苗联合免疫组(MB43+rFPV-IFN-γ)及rIFN-γ和MB43弱毒疫苗联合免疫组(MB43+rIFN-γ)在免疫后第2周即可检出ELISA抗体,比MB43疫苗单独免疫组早1周.用IBDV Gx株攻击后,MB43+rFPV-IFN-γ组和MB43+rIFN-γ组免疫鸡的脾只有个别淋巴细胞核浓缩、核崩解,少数滤泡萎缩变性坏死;胸腺损伤程度轻于MB43疫苗单独免疫组和非免疫对照组.免疫后1周,3个免疫组外周血CD8+T淋巴细胞含量均显著高于非免疫对照组,CD4+T淋巴细胞含量变化不明显;攻毒后第2周,3个疫苗免疫组CD4+、CD8+T淋巴细胞含量均显著升高,各组之间CD4+、CD8+T淋巴细胞含量无明显差异.证实,rFPV-IFN-γ和rIFN-γ可加强疫苗的细胞免疫和体液免疫应答.     

牛分枝杆菌esat-6和mpb70-mpb83基因DNA疫苗的免疫效果

用PCR技术和重叠延伸剪接技术获得牛分枝杆菌esat-6基因和mpb70-mpb83融合基因,连接真核表达载体pcDNA3.1(+),构建了重组质粒pCE6和pC70-83-E6。分4组免疫小鼠:pCE6组、pC70-83-E6组、pcDNA3.1(+)和PBS对照组,采用间接ELISA法检测免疫小鼠血清特异性抗体水平,MTT法检测免疫小鼠脾淋巴细胞增殖情况和IFN-γ分泌情况。结果表明,2重组质粒免疫组小鼠的血清抗体水平持续上升,而2对照组始终维持在较低水平,且pC70-83-E6组小鼠的抗体水平高于pCE6组。经PPD刺激后,pCE6组和pC70-83-E6组小鼠的SI值与2对照组均差异显著(P<0.05),2重组质粒免疫组间差异不显著(P>0.05);2重组质粒免疫小鼠脾细胞产生的IFN-γ均显著高于2对照组(P<0.05),且pC70-83-E6组明显高于其他3组(P<0.05)。证实本试验构建的2种牛分枝杆菌DNA疫苗可有效诱导实验动物产生体液免疫和细胞免疫应答。
